Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.

Lamborghini licenses MIT’s Cobalt-free organic battery tech for EVs – ET Auto

Baua Electric

The chemists developed a battery cathode based on organic materials, which could reduce the EV industry’s reliance on scarce metals. This material consists of many layers of TAQ, an organic small molecule that contains three fused hexagonal rings. Automaker Lamborghini has licensed the patent on the technology.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

New ionic liquid biomass pretreatment method eliminates need for enzymes, reduces water use

Green Car Congress

We’re then able to separate the pretreatment solution into two phases, a sugar-rich water phase for recovery and a lignin-rich ionic liquid phase for recycling. As an added bonus, our new pretreatment technique uses a lot less water than previous pretreatments. —Blake Simmons, corresponding author. —Blake Simmons.
